Promestriene (INN) (brand names Colpotrofin, Colpotrophine, Delipoderm), also known as estradiol 3-propyl 17β-methyl diether, is a synthetic estrogen which is used topically in a 1% cream formulation for the treatment of vaginal atrophy in women.[1][2][3][4][5] It is the 3-propyl and 17β-methyl diether of estradiol and does not appear to convert into estradiol in the body.[1][6] Promestriene is minimally absorbed and appears to have negligible systemic estrogenic effect.[1] The drug has been described as a tropic agent and antiseborrheic.[2] It has not been found to be effective in the treatment of pattern hair loss or other conditions of cutaneous androgenization.[7][8] Promestriene was first introduced in France in 1974 and has been marketed in 34 countries worldwide.[1] It has been used in millions of women.[1]
